Personal Life

Dr. Dixon grew up in a small suburb of Pittsburgh, PA called the North Hills and married his high school sweetheart who grew up nearby in North Allegheny. They have been married for 25 wonderful years now and have two amazing children, Breanna and Nate. The Dixons feel very fortunate to be able to provide a good home to needy animals, so the family also includes three dogs and five cats.

When Dr. Dixon isn’t at the practice or teaching at UW, he loves watching his kids play sports and spending his free time with their activities. He also runs, bikes, and enjoys the many activities that the Pacific Northwest has to offer.

Dr. Dixon feels privileged to live and work in such a vibrant and exciting community, one that has such world-recognized leaders in both medicine and dentistry, and outstanding local institutions like Seattle Children’s Hospital, the University of Washington, and the Hutch Research Institution. Over the years, he has served in many different community roles and leadership positions, and looks forward to a future filled with service to the Seattle community.
